Question

What are the main symptoms?

Answer

Mental Retardation (MR) refers to a significant and clear below-average intellectual and motor development during a child’s growth period, making it difficult to adapt to the demands of the objective environment. Experts point out that if an infant under one year of age shows one or more of the following abnormal behaviors, it highly suggests the possibility of MR.

  • Long-term lack of appetite, failure to suckle, making breastfeeding difficult, and prone to vomiting.
  • Constantly sleeping, difficult to wake up, or excessive sleep.
